Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider a hypothetical element that absorbs wavelengths of 450 nm, 500 nm, and 600 nm. If you were to see its absorption spectrum, which colors would be darkest?

💡 Hint: Think about what happens to the light when it encounters the element.

Challenge 2 Hard

Explain the importance of using absorption spectra in determining the composition of distant stars.

💡 Hint: Consider how distant observations rely on light gathered from those stars.
